Definitions

  • the present invention relates to a low-frequency treatment device to use in a bath.
  • Low-frequency treatment devices using commercialized ac source are not necessarily adequate because they may cause pain and/or burn when used in a bath, specifically in a bath tub, for a simultaneous thermotherapy.
  • batteries are employed to power a low-frequency treatment device when it is used in a bath.
  • a conventional device has the drawbacks that it renders attainment of the desired efficacy very difficult because batteries usually provide a relatively low voltage; and that it requires an expensive voltage increasing means such as a converter in case a relatively high voltage must be taken from a battery.
  • thermotherapy involves the problem that load resistance variation such as that with the distance between the electrodes or the conditions of the subject's skin renders application of a constant voltage to the subject's skin very difficult.
  • the present inventor investigated various means which overcome these drawbacks of a conventional device. As the result, the present inventor found that even when a battery is used a stablized voltage can be applied to the subject's skin by connecting a battery in series with a main current path of a switching transistor and a pair of electrodes which come into contact with the subject's skin when in use; and controlling the conduction of the switching transistor with an oscillating means that generates a surged treatment wave at a prescribed time interval.
  • the present invention relates to a low-frequency treatment device directed to use in a bath, characterized in that it comprises a pair of electrodes; a switching transistor; a battery connected in series with the pair of electrodes and a main current path of said switching transistor; and means for oscillating a surged treatment wave at a prescribed time interval, said oscillating means being used to control the conduction of said switching transistor.
  • reference numerals 1 and 2 designate electrodes; 3, switching transistor; 4, battery; 5 and 6, oscillators; T, transistor; R, resistor; and C, capacitor.
  • Fig. 1 is the block diagram of an embodiment according to the invention, wherein an electrode pair (1) and (2) and a main current path of a switching transistor (3) are connected in series with a battery (4).
  • the output terminal of oscillator (5) generating a low-frequency square wave as shown in Fig. 2 is connected with the input terminal of another oscillator (6) that generates a treatment wave with a relatively high frequency as shown in Fig.3.
  • the output terminal of oscillator (6) is connected with the base of switching transistor (3).
  • oscillator (6) Since oscillator (6) is arranged in such manner that it gener­ates a treatment voltage only when oscillator (5) provides a non-zero output voltage, switching transistor (3) becomes conductive at a time interval in accordance with the waveform as shown in FIG. 4. Thus, the subject's body in contact with electrode pair (1) and (2) is interruptedly energized with a surged treatment wave as shown in FIG. 4.
  • FIG. 5 is the circuit of another embodiment according to the invention, wherein a multivibrator as oscillator (5) comprising transistors T1 and T2 is used to generate a square wave of a frequency of about 0.1-10 Hz, desirably, 0.5-5 Hz.
  • the output of multivibrator (5) is supplied to another multi­vibrator generating a square wave with a pulse width of 1.500-­1/10 seconds and pulse interval of 1/100-1/5 seconds through an emitter follower that comprises resistor R5 and transistor T4.
  • the latter multivibrator corresponding to oscillator (5) in FIG.1 is actuated to make switching transistor (3), connected with the output terminal of transistor T5, conductive only when multivibrator (5) provides a non-zero output voltage.
  • the subject's body in contact with the pair of electrodes (1) and (2) is energized with a surged treatment wave in an inter­rupted manner as shown in FIG. 4.
  • the internal resistance of switching transistor (3) is lowered to below 10 ohms by supplying an excessive positive current to the base of switching transistor (3) to effect saturation and is several percents of the equivalent resistance of the subject's skin on the electrode pair even when it is assumed that the equivalent resistance is 1,000 ohms, the voltage across the subject's skin can be kept to an approximately prescribed level even when the equivalent resis­tance varies during one or repeated treatments.
  • Oscillator (6) in the embodiment as shown in FIG. 1 may be a blocking oscillator as shown in FIG. 6 that oscillates a diphasic action potential wave.
  • the subject's skin interruptedly receives a surged diphasic action potential wave.
  • the switching transistor having a main current path controlled by the electrode pair and low-frequency oscillator is connected in series directly with the battery, a higher voltage utilization factor can be attained.
  • the pair of electrodes and the switching transistor having a main current path controlled by the low-frequency oscillator are connected in series directly with the battery, a sufficient treatment voltage can be applied to the subject's skin without causing electric shock even when used in bath tub.
  • the internal resistance of the switching transistor can be extremely lowered with respect to the equivalent resistance of the subject's skin that is in contact with the pair of electrodes, the subject's skin receives a constant treatment voltage.
  • the treatment wave interruptedly applied to the subject's skin is surged in a low-frequency voltage, it can cause an appropriate relaxation.
  • the treatment device according to the invention can be used safely even in a bath tub, the affected site such as that in the scalp can be efficiently massaged.
